Video codecs remain an area of active research and development. The current generation video codec is H.264 – in widespread usage on the Internet. Cisco has actively worked towards making H.264 the foundation of real-time communications on the web. The next generation codecs are just beginning to emerge. There are two of note – Google’s proprietary VP9 codec, and the industry standard H.265 (HEVC) codec, which is the successor to H.264 (AVC).
